Vibration reduction will be an important contributor to the success of future earth observing platforms. Unwanted motion in the micrometer to nanometer range must be prevented from interfering with components requiring precise alignment and pointing such as telescopes and interferometers. Active structural control employing smart materials is an ideal technology for accomplishing this goal, howeve ...

Active Control eXperts (ACX), Inc. proposes a Phase I research and development effort for the development, conceptual design, and proof-of-concept experiment of a hybrid active/passive sound attenuation system for aircraft interiors. While the attenuation of structural vibration and structure-borne sound using passive means is the current state-of-the-art, and active structural acoustic control (A ...

Terrain data needs on the battlefield are generating greater military requirements for new, rapid feature mapping capabilities. Unfortunately, current methods are woefully inadequate to meet the needs of the modern digitized battlefield in which thecommander must have the ability to rapidly obtain accurate terrain information and topographic products. Terrain Reasoning methods will allow more ra ...

This project concerns the development of a sensor intended to remotely monitor plant stress using active stimulation of plant chlorophyll fluorescence. The intensity and spectral band shape of leaf chlorophyll fluorescence in green plants has been linked to the physiological status of the plants and thus provides a good indicator of plant health. The proposed sensor will measure the relative inten ...

This SBIR Phase1 project will involve the development of a novel method of simultaneously measuring multiple trace chemical species in jet engine exhaust, based upon an extension of the technology of tunable diode laser (TDL) spectroscopy. We will develop and demonstrate a new means of combining the light from two or more diode lasers into a single analysis beam. This will enable a multiplication ...

High pressure ratio compressor operation is enabled by blade cooling, based on an evaporation / condensation cycle. The blade or blisk temperature is defined by the vaporization temperature of a working fluid internal to the blade, with heat transferred to an integral condenser at each blade root. This approach provides heat rejection to a cool, low pressure fluid, such as engine lubricating oil, ...

Prevention of catastrophic failure of engine components is a major goal to the subtopic. Catastrophic failures of turbine engines are often caused by vibration-induced compressor and fan blade fatigue fractures. Existing capacitance systems have been unable to accurately measure blade vibration due to limited spatial resolution and limited system bandwidth. The proposed effort will develop a new c ...

High speed x-ray imaging is extremely important for several military and civilian applications such as imaging exploding land mines, high speed computed tomography for medical imaging, time resolved x-ray diffraction of biological systems, and drugdevelopment research. The advent of high flux, micro-focused, flash x-ray sources have now facilitated high-speed x-ray imaging in laboratory environme ...

A critically important region of the electromagnetic spectrum is the hard X-ray/soft gamma-ray band from 10 KeV to a few MeVs. In this band, a wealth of astrophysical processes occur in an even greater diversity of astrophysical objects and phenomena, both on a compact and diffuse scale. Surprisingly, for such a pivotal region of the spectrum, the high energy sky is still quite unexplored in that ...
